(Phys.org)—A team of researchers with Warsaw University Observatory, Ohio State University and the University of Warwick has found evidence that suggests there are far fewer Jupiter-sized rogue planets roaming the Milky Way galaxy than prior surveys have shown. In their paper published in the journal Nature, the group describes using data compiled from the Optical Gravitational Lensing Experiment to analyze light curves of approximately 50 million stars for the period 2010 to 2015 and what they found by doing so.
